Strixhaven: School of Mages

Snow Day | Instant | | Tap up to two target creatures. Those creatures don't untap during their controller's next untap step. Draw two cards, then discard a card. | Forrest Imel

Divide by Zero | Instant | | Return target spell or permanent with mana value 1 or greater to its owner's hand. Learn. (You may reveal a Lesson card you own from outside the game and put it into your hand, or discard a card to draw a card.) | Liiga Smilshkalne

Test of Talents | Instant | | Counter target instant or sorcery spell. Search its controller's graveyard, hand, and library for any number of cards with the same name as that spell and exile them. That player shuffles, then draws a card for each card exiled from their hand this way. | Lie Setiawan

Practical Research | Instant | | Draw four cards. Then discard two cards unless you discard an instant or sorcery card. | Ekaterina Burmak

Creative Outburst | Instant | | Creative Outburst deals 5 damage to any target. Look at the top five cards of your library. Put one of them into your hand and the rest on the bottom of your library in a random order. {U/R}{U/R}, Discard Creative Outburst: Create a Treasure token. | Igor Kieryluk

Decisive Denial | Instant | | Choose one — • Target creature you control fights target creature you don't control. (Each deals damage equal to its power to the other.) • Counter target noncreature spell unless its controller pays {3}. | Lorenzo Mastroianni
